摘要:Abstract(#br)The topographic signature of a mountain belt depends on the interplay of tectonic, climatic and erosional processes, whose relative importance changes over times, while quantifying these processes and their rates at specific times remains a challenge. The eastern And...

摘要:Exhumed basement rocks are often dissected by faults, the latter controlling physical parameters such as rock strength, porosity, or permeability. Knowledge on the three-dimensional (3-D) geometry of the fault pattern and its continuation with depth is therefore of paramount impo...

摘要:Abstract(#br)To constrain the depth-dependence of in situ 14 C production we measured the cosmogenic 14 C concentration of quartz separates along a quartzite core from the Leymon High site in northwest Spain. A total of 16 quartz samples were measured over a depth range of 1...

摘要:Abstract(#br)The geomorphic evolution of the Makran Range of SE-Iran and SW-Pakistan has been controlled by the prevailing SW-Asian monsoon and Mediterranean winter rainfall climate and the surface uplift processes resulting from the Arabia–Eurasia collision. The impact of c...

摘要:Abstract(#br)We report concentrations of in situ cosmogenic 10 Be and 21 Ne from coexisting quartz and sanidine separates and of cosmogenic 3 He in coexisting Fe–Ti-oxide minerals from ignimbritic successions of northern Chile (Oxaya and Lauca ignimbrites). New mineral-isoto...

摘要:Abstract(#br)Based on a compilation of published combined 10 Be and 21 Ne cosmogenic nuclide data sets from quartz samples obtained at ETH Zürich we assess the 21 Ne/ 10 Be (P21/P10) production rate ratio with the goal to determine the 21 Ne production rate (P21) in quartz. ...

摘要:Abstract(#br)The quantification of geomorphic process rates on the outcrop- and the orogen-scale is important to describe accurately the interaction between the relative effects of erosion, tectonics and climate on landscape evolution. We report single and paired cosmogenic ...

摘要:Abstract(#br)It is shown that thermally polarized 3 He gas can be used to measure important physical parameters and to design, test, and tune imaging sequences. The bulk values of T 1 , T 2 , and the diffusion coefficient were measured in a glass cell containing a mixture of...

摘要:Abstract(#br)We present the improved performance of the modified in situ cosmogenic 14 C extraction system at ETH Zürich. Samples are now processed faster (2 days in total) and are measured with a high analytical precision of usually <2% using the gas ion source of the MICAD...

摘要:Abstract(#br)In 2001, a small H4 chondrite, Frontier Mountain (FRO) 01149, was found on a glacially eroded surface near the top of Frontier Mountain, Antarctica, about 600 m above the present ice level. The metal and sulphides are almost completely oxidized due to terrestria...
